22) to whom it may concern..-

Be it known that I, GEORGE W. WILLIAMS, a citizen of the United States, and a resident of Waco, in the county of McLennan and State of TeXas, have in vented a new and Improved Cotton-Valve, of which the following is a full, clear, and exact description.

This invention relates to 'a valve vfor controlling the passage of cotton from the cotton bin or warehouse to the elevator carrying it to the gins; and the object is to provide a valve which may be used in connection with an elevator consisting in two batteries or divisions, so that one division may be cut out while the other is in operation.

To this end the invention consists in a valve having a casing with two outlets, each associated with an independent valve-plate and leading from a single inlet.

For further information concerning the application and use of the invention reference may be had to my prior patent for cotton-elevators, No. 641,176, dated January 9, 1900.

This specification is the disclosure of one form of the invention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a plan view of the invention with parts broken away. Fig. 2 is an irregular section on the line 2 2 of Fig. 1, and Fig. 3 is a cross-section on the line 3 3 of Fig. 1.

The valve has a casing or chamber formed, preferably, of sheet metal, with a plane top wall a and a similar bottom wall a, the side walls a converging toward the inlet a of the casing. This inlet is in the form of a short tube or collar of circular cross-section, so that it may be engaged with theconduit leading from the source of cotton-supply. If desired, the top wall a of the casing may be furnished with a manhole and cover a which may be of any desired form. The end of the casing opposite the inlet a is taken up by the two outlets 0. which are also in the form of tubes projected from the casing, so that they may be respectively connected with the divisions Serial No. 12,110v (N0 model.)

of the battery of cotton-elevators, whereby to' conduct the cotton to the gins, as will be understood by persons skilled in the art.

Within the casing and extending longitudinally thereof is an intermediately-disposed partition b,standing perpendicularly between the top and bottom walls a and extending from the outlet end of the casing to a point fa-little past the middle of the casing. This @partition I) divides the casing into two passages, which lead, respectively, to'the outlet- "tubes 0. and both of which communicate with the contracted portion of the casing at the inlet end thereof. Situated at each side of the partition 1) are the valveplates or valves proper, 0. These valve-plates when in closed position, as shown in Fig. 2, lie diagonally in the casing, and the valves are hung so that they will permit the free passage of the cotton from the inlet to the outlets of the casing, but will prevent the return of the cotton or the back passage of the air blast through the casing. The valve-plates c are hung at their upper ends, respectively, by means of short sections of stout woven fabric 0, which sections are fastened to the valveplates by bending the adjacent edges of the plates over the fabric to clamp the fabric on the plates. The sections of fabric 0' which form the hinges of the valve-plates are fastened to the under side of the top wall a of the casing by means of a cleat 0 which extends transversely across the casing and is fastened thereto, as shown. The lower or free ends of the valve-plate c are provided with flaps or tongues 0 also of stout fabric, and fastened to the valve-plates in the same manner as the fabric 0, all of which. is shown in Fig. 2. The flaps c serve to form approximately hermetic connection with the bottom walls a, of the casing when the valve-plates are in the position shown in Fig. 2. For effectively closing the space between the side edges of the valve-plates and the side walls a and partition 6 I provide each valve-plate with two aprons 0 which are essentially triangular in form (see Fig. 2) and which have their diagonal lower edges fastened to the valve -plates 0, and their horizontal upper edges are secured between the upper edge of the partition b and the top wall a of the casing, these parts being secured together by screws or other suitable fastening devices. Should the back pressure of air enter the casing or, in other words, should a current of air flow into the casing through the outlets of, the valve-plates will be thrown down to the position shown in Fig. 2, thus causing the flaps c and aprons c to distend outward against the sides and bottom of the casing, and the passages between the partition I) and the side walls of the casing will thus be effectively closed. The construction provided will, however, ofier no material resistance to the blasts of air passing in the regular course.

In the practical use of this valve the divisions of the elevator which are respectively connected with the outlets a are alternately cut out of action,and when one division is cut out of action a back pressure is created therein, which serves instantly and automatically to close the valve-plate c which has command of such division. Owing to the peculiar construction of this device the operation of the valve-plates is rendered unfailing and the parts are not subject to breakage when subjected to the strain incident to their operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A valve, having a casing, a valve proper or valve-plate mounted therein, and a side apron fastened to the valve-plate and to the casing, for the purpose described.

2. A valve, having a valve-casing with an inlet-orifice and two outlet-orifices, the outlet-orifices being arranged side by side and having their axes disposed parallel to the axis of the inlet, a partition fitted in the easing intermediate the outlet-orifices and forming two passages which constitute continuations of the outlet-orifices, and valves arranged in the casing respectively at the sides of the partition to prevent backflowing currents in the casing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE W. WILLIAMS.
